Final answer:
The total magnification achieved with a 100X oil immersion lens and 10X binocular eyepieces is 1000x. This is determined by multiplying the magnification of the objective lens (100X) by that of the eyepieces (10X). The correct option is d.
Step-by-step explanation:
The total magnification achieved when using a 100X oil immersion lens with 10X binocular eyepieces is calculated by multiplying the magnification of the objective lens by the magnification of the eyepieces.
Therefore, if the objective lens magnifies 100X and the eyepieces magnify 10X, the total magnification would be:
(100x) × (10x) = 1000x.
This is a common calculation in microscopy where the magnification provided by the objective lens is compounded by the magnification from the eyepiece lens.
Therefore, the correct option is d.
